# This file serves as documentation for config parameters of delta
# style printers. One may copy and edit this file to configure a new
# delta printer. Only parameters unique to delta printers are
# described here - see the "example.cfg" file for description of
# common config parameters.
# DO NOT COPY THIS FILE WITHOUT CAREFULLY READING AND UPDATING IT
# FIRST. Incorrectly configured parameters may cause damage.
# The stepper_a section describes the stepper controlling the front
# left tower (at 210 degrees). This section also controls the homing
# parameters (homing_speed, homing_retract_dist) for all towers.

# Length (in mm) of the diagonal rod that connects this tower to the
# print head. This parameter must be provided for stepper_a; for
# stepper_b and stepper_c this parameter defaults to the value
# specified for stepper_a.
#angle:
# This option specifies the angle (in degrees) that the tower is
# at. The default is 210 for stepper_a, 330 for stepper_b, and 90
# for stepper_c.

# right tower (at 330 degrees).

kinematics: delta
# This option must be "delta" for linear delta printers.
max_velocity: 300
# Maximum velocity (in mm/s) of the toolhead relative to the
# print. This parameter must be specified.
max_accel: 3000
# Maximum acceleration (in mm/s^2) of the toolhead relative to the
# print. This parameter must be specified.
max_z_velocity: 150
# For delta printers this limits the maximum velocity (in mm/s) of
# moves with z axis movement. This setting can be used to reduce the
# maximum speed of up/down moves (which require a higher step rate
# than other moves on a delta printer). The default is to use
# max_velocity for max_z_velocity.
delta_radius: 174.75
# Radius (in mm) of the horizontal circle formed by the three linear
# axis towers. This parameter may also be calculated as:
# delta_radius = smooth_rod_offset - effector_offset - carriage_offset
# This parameter must be provided.
